【问题描述】:
我目前正在向 Azure 发布一个非常基本的烧瓶应用程序,尽管我在 Google 上找到了任何东西,但这些天我都没有成功。
我的架构非常简单(我将在下面展示它,因为我认为这不是问题的根源)并且我有一个 web.config 文件:
文件“web.config”:
<?xml version="1.0"?>
<configuration>
<appSettings>
<add key="WSGI_HANDLER" value="MentorQuestFlask.app"/>
<add key="PYTHONPATH" value="D:\home\site\wwwroot"/>
<add key="WSGI_LOG" value="D:\home\LogFiles\wfastcgi.log"/>
</appSettings>
<system.webServer>
<handlers>
<add name="PythonHandler" path="handler.fcgi" verb="*" modules="FastCgiModule" scriptProcessor="D:\home\python364x64\python.exe|D:\home\python364x64\wfastcgi.py" resourceType="Unspecified" requireAccess="Script"/>
</handlers>
<rewrite>
<rules>
<rule name="Static Files" stopProcessing="true">
<conditions>
<add input="true" pattern="false" />
</conditions>
</rule>
<rule name="Configure Python" stopProcessing="true">
<match url="(.*)" ignoreCase="false" />
<conditions>
<add input="{REQUEST_URI}" pattern="^/static/.*" ignoreCase="true" negate="true" />
</conditions>
<action type="Rewrite" url="handler.fcgi/{R:1}" appendQueryString="true" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>
在 Azure 中,我添加了扩展:Python 3.6.4 x64 在另一个线程之后,我在配置选项卡中添加了 Python 3.6:picture of the configuration zone
在我添加的路径映射中:
扩展名:fastCgi
脚本处理器:D:\home\python362x86\python.exe
参数:D:\home\python362x86\wfastcgi.py
最后在应用程序设置中,WEBSITE_USE_PLACEHOLDER 设置为 0。
但没有任何效果。在网站上,我看到以下错误:
“由于发生内部服务器错误,页面无法显示。”
所以我用 Kudu 来显示如下(在这个文字下面)
我的问题是:
- 似乎没有安装任何软件包(flask 错误)
- web.config 似乎配置不正确。
我尝试了几种不同的配置,但都没有奏效,而且我的想法很有限......
感谢您的帮助或建议?
问候,
查尔斯

<h3>HTTP Error 500.0 - Internal Server Error</h3>
<h4>The page cannot be displayed because an internal server error has occurred.</h4>
</div>
<div class="content-container">
<fieldset><h4>Most likely causes:</h4>
<ul> <li>IIS received the request; however, an internal error occurred during the processing of the request. The root cause of this error depends on which module handles the request and what was happening in the worker process when this error occurred.</li> <li>IIS was not able to access the web.config file for the Web site or application. This can occur if the NTFS permissions are set incorrectly.</li> <li>IIS was not able to process configuration for the Web site or application.</li> <li>The authenticated user does not have permission to use this DLL.</li> <li>The request is mapped to a managed handler but the .NET Extensibility Feature is not installed.</li> </ul>
</fieldset>
</div>
<div class="content-container">
<fieldset><h4>Things you can try:</h4>
<ul> <li>Ensure that the NTFS permissions for the web.config file are correct and allow access to the Web server's machine account.</li> <li>Check the event logs to see if any additional information was logged.</li> <li>Verify the permissions for the DLL.</li> <li>Install the .NET Extensibility feature if the request is mapped to a managed handler.</li> <li>Create a tracing rule to track failed requests for this HTTP status code.

导师任务:
我有一个包含所有包的 requirements.txt 文件
文件:“runserver.py”:
from os import environ
from MentorQuestFlask import app
if __name__ == '__main__':
HOST = environ.get('SERVER_HOST', 'localhost')
try:
PORT = int(environ.get('SERVER_PORT', '5555'))
except ValueError:
PORT = 5555
app.run(HOST, PORT)
MentorQuest > MentorQuestFlask:
文件“init.py”:

文件:“view.py”:
from MentorQuestFlask import app

return 'Hello World!'
【问题讨论】:
-
您是手动部署还是从 GitHub 部署?
-
我正在持续部署中,确实与 GitHub 有链接
